.measure

Syntax

.measure tran meas_name trig ... targ ...

Description

Defines the measurement that is performed for propagation, delay, rise time, fall time, average voltage, peak-to-peak voltage, and minimum and maximum voltage over a specified period, and over a number of other user-defined variables. The measurement can be used for power analysis on elements or subcircuits (see Examples).

The .measure statement can also be embedded within a subcircuit definition in the netlist file. The measure name is appended with the call path name from the top level to the instances of the subcircuit. The .measure statement can also be used to perform the measurement of all output variables, including expression probes already defined in the .probe expr() statement.

The Spectre FX simulator supports linked measure statements applicable for all the measure functions listed below. Some measure statements may depend on others by having the names of other measures in expressions (instead of parameters). These expressions cannot contain node voltages and element currents. To avoid confusion, linked measure statements must be in the same scope (that is, either at the top level or in the same subcircuit definition).
